(Cl. 23S- 88) 2 Claims.

This invention relates to new and useful improvements in a womans diary land marital calculator.

More specifically, the present invention proposes the construction of. an improved womans diary and marital calculator in the form of a booklet prepared to include information regarding the biological problems of childbirth and the method of using the booklet, a diary for recording pertinent information regarding menstrual cycles and a calculator to be used for determining sterile and fertile periods on the basis of recorded information and in accordance with the so-called Ogino-Knaus, rhythmic or safe period method of birth control.

Still further, the present invention .proposes constructing thev diary to record information regarding the periods of menstruation and phenomena accompanying them, f great importance in every womans life and which enables the woman to control the phenomena, supply valuable information to the physician, if his assistance is required, and to operate the calculator on the basis of certain information obtained from the diary.

Another object of the present invention proposes constructing the calculator so that by turning a movable dial relative to a fixed dial in accordance with certain information obtained from the diary it is possible for a woman to d etermine, for each menstrual cycle, the period of fertility making family planning a simple matter by making use of the fertile periods for intercourse when a child is desired or by abstaining from intercourse during the fertile periods if pregnancy is not wanted.

As a further object, the present invention proposes constructing the calculator so that it will give the duration of the fertile periods for each menstrual cycle in terms of days of the month eliminating involved calculations which often lead to error; making it a simple matter to arrange procreation intentionally and to secure birth control without the use of contraceptives which prevent the male sperm from reaching the womans organism which ofttimes has a harmful effect on the womans health.

It is a further object of the present invention to construct a womans diary and marital calculator which is simple to use, which is effective for its intended purpose and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, ref-- erence will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

On the accompanying drawings forming a material part of this disclosure:

Fig. 5 is a perspective view of the rotatable disc of the calculator, per se.

Fig. 6 is an enlarged detailed view of the lower right hand corner of Fig. 3 showing the calculator before the rotatable disc is mounted in position.

The womans diaryand marital calculator, according to the present invention, is in the form of a booklet I0 having a front cover I I, a rear cover I2 and a plurality of leaves I4 between the covers I I and I2. The inner page of the front cover I I and the pages of the leaves I4, except for the rear page I4a of the last leaf I4 and the inner page I 2' of the rear cover I2, are imprinted with pertinent information regarding the biological problems of childbirth and the manner of using the diary and calculator, to be hereinafter described. The number of leaves I4 embodied in the booklet I 0 is not important and their number can be increased or decreased in accordance with the amount of information which it might be desired to imprint thereon.

The front face of the front cover I I is attractively imprinted with the name of the booklet I5 and the number I6 of the year 1952 covered by the booklet as well as other material which enhances the appearance of the booklet I0.

Imprinted on the rear page IllEL of the last leaf I4 of the booklet I 0, there is a diary I1 which covers one complete year, see Fig. 3. In the booklet I illustrated on the drawings, the diary I l covers the calendar year 1952; it being understood of course, that the diary I1 will be similarly arranged for any other calendar year. The diary I 'I is subdivided into three lines of four calendar months with each day of the month being indicated by a suitably numbered box I8. The day of the month numbers are positioned at one of the ends of the boxes I8 leaving a blank space within each box for the notation of pertinent information as will become clear as this specification proceeds. At the ends of each line of four calendar months, there are boxes I9 imprinted with letters designating the days of the week as follows:

S for Sunday M for Monday TU for Tuesday W for Wednesday TH for Thursday F for Friday S for Saturday eneath each line of four calendar months. there is provided a blank space 2|) for therecordation of pertinentthings which take place during any one calendar month and which might possibly effect the start of the next menstrual cycle causing it to be premature or to be delayed', and which might so effect the normal` menstrual' cycle as to limit or even prevent the use of'V theA calculator.

In the upper right hand corner of the diary I1, there are provided ten. small. boxes. 21. for recording the length in number of days. of. the last ten menstrual cycles of the preceding calendar year. The recorded' numbers are essential in determining the limit of" fluctuations when making fertile period determinations in connection with each of' the rst eight months ofthe calendar year for which the boolrlet lil'v has been prepared.

In the upper right hand' corner' of each of the month designati-ons of the diaryv Il', there' is provided av small boxr 22 for recording the length of the last menstrual cycle in the total number of' days. In the upper left hand corner oi each of the month designations ofthe diary |11, there is a box' 23 for recording the limits of the fluctuations of the menstrual cycles of the preceding eight months. Those limits ofl fluctuations are recorded in pairs of numbersone indicating the least number of days and the other indicating the greatest number of days.

Thel calculator isy mounted on the lower portion of the inner page i2a of the back cover i2 and consists'of a fixed dial 2li", see Figs. 3 and 6, im'- printed'on the page I2@ and overwhich a rotatable dial 25, see Figs. 3 and 5, is mounted using a grommet 26, see Figs. 3 and 4. The xed dial 24, see Fig. 3', is somevi/'hatv larger than the rotatable dial 25 and beyond the periphery or the rotatable' dial 25, the fixed: dial 24 has' an arcuate area subdivided into a plurality of small boxes 2 each' imprinted with a number. There are fifteen boxes 2l each having a number with the numbers running consecutively from 21 to 35, see Figs. 3" and 5.

The rotatable discv 25 immediately adjacent the periphery has a segmental area subdivided into a plurality of boxes 23. Thel boxes 28 are thirty-one in number and each is imprintedA with a number; with the numbers running consecutively from 1 to 31 designating the days of the month or more correctly the first day of a menstrual cycle. Closely adjacent the box 28 provided with the number 3|, the rotatable disc 25' is formed with a radially elongated slot 29' for the months of the year which have thirty daysnamely April, June, September' and Nofvember; Spacedl circumierentially and radially inward from the slots 29, the rotatable disc' 25" has another radially elongated slot Sil' for the months of the year'which have thirty-one daysnamely, January, March, May, July, August, October and December. Between the slots ZS and" 30 and radially inward from the slot 3|), the` rotatable disc has a third elongated slot 3| for the month of February which has twenty-eight days ina normal year and twenty-nine days in leap years.

Immediately below the rotatablel discr 25v andy in alignment with the slots 29, 38. and 3|, the' fixed disc 24, see particularly Figs. 3 and 6, has spaced sets of two numbers each. Thev sets of numbers are arranged in circles and consistsof an outer circle of numbers 32 in alignment with the slot 29, an intermediate circle oi numbers 33 in alignment with the slot 30 and an inner circle of numbers 34 in alignment With the slot 3|. Thus, in each. rotative position of the rotatable disc 25v relative to the fixed disc 24' one of the sets of numbers 32, 33 and 34 will be aligned with the respective slots 29, 30 and 3|, as shown in. Fig. 3'- vThe sets of numbers 32, 33 and 34 designate the starting and ending days, in day dates, of. the fertile periods of each menstrual cycle.

The inner'page I2.Er of the back cover l2, above the calculator is imprinted with an area 35 which gives information on how to keep the diary I1. The area 35 has duplicated therein a portion lla1 of the` diary Il corresponding toV the-months of July and August. Alongside of theportion lla, the area 35 includes an explanation of the symbols to be-usedi'n marking the diary. Those symbols are as follows: o-First day of menstrual cycle. `"-Fertile period. m-M'enstruati'on .r--Intercourse Those symbols are to be marked withinv the boxes t8. immediately adjacentV the respective day numbers, as shown in.. the portion Ila of the area S5. As theA year 1952 is a leap year, the bottom of the area 35 isf imprinted with. information regarding adjustments to be made iny view of the fact that the calculator only provi-des for twentyeight days inf February.` rI'he imprintedinformation` reads as follows-:

IMPORTANT-Re: February 1952Y ('29 days) :l

1952VV is a leap year and thel calculator provides only 28 daysI for February. Therefore, when the: iirst day of the'I menstruation ialls in February' 19512 and the: fertility period begins in March, it will be necessary' to lengthen'. the March; fertilityv period byl one day at they beginning..

This, of course, applies only toV leap year' and isto-be ignored iin normal yearsofA 365 days.

To illustrate the manner of using the diary and calculator letus assume' a hypothetical case for the months of July'and August 1952, in which the4 last;menstrual` cyclehad 32 days and in which menstrual' bleeding atz the start of the'next menstrual cycle was first noted on July 23rd. That is the situation which is illustrated in the" example imprinted within the area 35 at the topl of the inner page |221- of" the back cover |21 The number 3-2 designating the length of the last menstrual cycle is then` written within the' box 22" for themonth of July and a small dot designatingv the start of menstrual bleeding and also `the start of theI next menstrual cycle is made withiny the box |18 for July' 23rd immediately to the righ-tv of thel numeral 23". Now let us assume tha-ttheflast eiglii't previous menstrual cycles were of 30, 34, 33, 31', 37, 32', 33'v and' 32` days in duration. The limits of fluctuation forthe last' eight menstrualv cycles are 3`0-34, and the difference is four days. The numbers 3'0" and 34' designatingthe limits of' fluctuation pertinent to the present menstrual cycle` are written Within the box 23 ofthe month ofl Au'gust, as shown within thearea 35'. In determining the limits of flue'- tuation, the last three cycles approached' the previous norm', soit is possiblel to' overlook. the one cycle off 37 days in determining the' maximum limit, particularly as that abnormal limit wasI known to be caused by a troublesome removal.

With, that pertinent` data.l entered in the diary i7, namely, July 23rd as the rst day of the new menstrual cycle, 32 days as the length of the last menstrual cycle and 30-34 as the limits of the last fluctuation. We then turn to the calculator and rotate the rotatable disc relative to the fixed dise 24 to align the numbered box 28 of the rotatable disc having the number 23, the

rst day of the new menstrual cycle, with the numbered box 2l of the xed disc having the number 36, see Fig. 3, which is the shortest limit of uctuation of the combination C-Sil. With the discs 24 and 25 in that position, we then look, with the slot 3G for the thirty-one day months, of which July is one, and obtain the answer S-l, see Fig. 3. 1f the month we were working in had been a thirty day month we would have looked in the slot 29 and obtained the answer 4 I i. working in had been February we would have looked in the slot 3l and obtained the answer G-|3. The slot 36 for July is used because the nrst day of the menstrual cycle tool; place in July on the 23rd day.

Four days must be added to the answer 3-10 f due to the difference in the limit of fluctuation for the current cycle) making a total of the 3rd to the 14th as the fertile period for the month of August and those days are so indicated in the respective boxes the example in the area 35. To determine the period of greatest fertility between the date of August 3rd and August 14th, it is customary to deduct the two days at each end of the period. Doing so, it is determined that the period of greatest fertility is between August 5th and the 12th and if pregnancy is desired intercourse should be had between those days.

Each day that menstrual bleeding continues, it is noted on the diary using the symbol (m) in each of the day blocks i 8 that bleeding continues. From the example illustrated within the area it will be noted that bleeding continued from July 23rd until July 26th-a periodof four days. The periods from July 27th to August 2nd and from August 15th to the start of the next menstrual cycle are the sterile periods during which copulation may be had without conception. Each copulation is indicated on the diary using the symbol (zr) and from the example within the area 35 it will be noted that intercourse was had on the following days of the sterile periods: July 27th, August 2nd, August 15th and August 18th.

The next menstrual cycle is indicated by the next start of menstrual bleeding and its dateprobable sometime in Augustis noted using the symbol (m) to denote the start of the next menstrual cycle when the procedure outlined above is repeated.

From the foregoing description, it is apparent that the present invention provides a simple method of determining and recording pertinent information regarding menstrual cycles. Keeping the diary and operating the calculator is so simple and requires only a knowledge of certain elementary rules; so that if anything goes wrong it will be due not to the shortcomings of the method but to inaccurate observations and lack of exactness in keeping the diary. The method 'has its shortcomings which arise mostly as a result of human failure; notwithstanding, the method is recognized as giving the same safety in practice as the best artificial contraceptives, Without their harmful effect on the woman.

By the same token if the month we were i8, using the symbol see While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications corning within the scope of the invention as dened in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:
